My bolding.My answer is a firm No, for I can see no logical reason why God's omniscience cannot be exactly that. Surely if our brains, that is to say the mechanism by which we have the ability to reason and act, is given to us by God, then I think we can assume predictability and foreknowledge of our actions. A designer creates a product and can even predict it's long-term performance and indicate its probable obsolesence date. But unlike an imperfect human, in the case of an omnipotent God there are by definition no probabilities or adjusted forecasts. We do what we're expected to do. God cannot be surprised, disappointed, delighted, angry or frustrated. Hume said: 'Whatever is, may not be'. But (with apologies to Hume) I would add to that 'except where it is ordained by God'. None of this is to say that God does or must exist.

In this case, it would not be God's omniscience that is killing the possibility of free-will, but the design. (ie, if the design of humans is such that it is perfectly predictable, we are not designed to have free-will in the first place.)
